SoundMeter 8 includes companion app for Apple Watch

SoundMeter 8.0 and SoundMeter Pro 4.0, which are both now available for download on the App Store, each include a companion app for Apple Watch. With the Watch app, you can monitor the current sound level, spectrum, and/or noise dose from your wrist (requires iOS 8.2 and iPhone 5 or later). These new versions of SoundMeter add other significant features, as well, including background sound level measurements and notifications of exceeded levels. The original sound level meter app for iPhone has now become the original sound level meter app for Apple Watch.

SoundMeter’s companion app for Apple Watch includes a separate screen for each of SoundMeter’s available tools running on the iPhone (new tools added to SoundMeter via in-app purchase are also supported in the companion app). Each tool can be started or stopped from the watch and current measurement values are updated on the watch display each second. The new notifications feature in SoundMeter allows the user to be notified on the Apple Watch when certain events occur. Notifications can be triggered when measurements stop (using the Auto-Stop feature) or when certain user-defined levels are exceeded. These notifications are supported in each of the Meter, Octave, and Dosimeter tools.

SoundMeter’s new ability to run in the background allows it to continue to run long-term measurements while other (non-audio) apps are in use. A complimentary new feature also allows the individual tools in SoundMeter to run independently. This means that users can run measurements in the Meter, Octave, and Dosimeter tools simultaneously. Users no longer need to worry about resetting the current measurement by switching to another tool (whether intentionally or accidentally). This makes SoundMeter more robust in terms of its ability to preserve acquired data until it can be saved more permanently in an image or data file.

The new versions of SoundMeter also include the following improvements:

  • Lx (percentile-exceeded sound level) measurements now use the same time and frequency weighting as the Lp measurement, instead of automatically switching to Fast and A weighting.
  • Frequency weighting may now be set to Flat, A, or C in the Dosimeter options menu (previously, the Dosimeter only allowed A weighting).
  • Meter, Octave, and Dosimeter tools now use local notifications to alert you when a measurement has finished or when selected levels have exceeded user-defined thresholds.
  • This release corrects a bug that could cause the device sensitivity for the built-in mic or the headset input to get corrupted when changing input gain selection with device units set to “FS.”

Notes:

  1. Octave and Dosimeter tools, Lx measurement and data file export capability are sold separately within SoundMeter via in-app purchase. These capabilities are all included with SoundMeter Pro.
  2. This SoundMeter update will require you to restore your in-app purchases (you will not be charged again for upgrades you have already purchased).
  3. Apple Watch compatibility requires iOS 8.2 and iPhone 5 or later.

SoundMeter Pro adds NC, RNC, NR reference curves and Octave data overlays

SoundMeter Pro 3 now offers the option to overlay noise criteria (NC), room noise criteria (RNC), or noise rating (NR) references curves over the live Octave analyzer bar graph. When NC or NR references curves are visible, SoundMeter Pro also calculates the NC or NR value, respectively. Speech interference level (SIL) is also calculated.

As in the recent update to SignalScope Pro, SoundMeter Pro’s Octave analyzer tool now offers the option to load whole or 1/3-octave spectrum data from exported Octave data files. Up to six sound spectrum curves can be overlaid on the live bar graph. It is possible to select the individual channels from which to load data when multiple channels of data exist within a single file. Also of note is the ability to overlay 1/3-octave data on a whole-octave bar graph and vice versa.

SoundMeter Pro 3 also features the following improvements:

  • The Octave tool now calculates Lp, Leq, and Lx values, regardless of which is currently being displayed.
  • The Octave tool calculates the noise criterion (NC) and speech interference level (SIL) as defined in ANSI S12.2-2008, as well as the noise rating (NR) level.
  • SoundMeter Pro 3 employs a new plotting framework for real-time data graphs and high resolution image export.
  • GPS coordinates, altitude, and accuracy may now optionally be saved with Octave analyzer data. Retrieving location information now works on iOS 8 for the Meter and Dosimeter tools, which can also export more detailed location information.
  • When viewing details for data files saved within the app, the Open In button now works properly on both iOS 7 and iOS 8. Depending on the file type and the apps installed and/or configured on your iOS device, options may be presented for emailing, previewing, printing or copying the file, in addition to opening the file in another app.

SoundMeter 7 offers the same enhancements as SoundMeter Pro 3, although some of the new features require upgrades which are available in SoundMeter via in-app purchase. These upgrades include the Octave Analyzer RTA Tool, Percentile-Exceeded Sound Levels, and Data Acquisition Support.

Faber Acoustical announces SoundMeter Pro for iOS

Building on the success of SoundMeter, which debuted on the iPhone App Store in August of 2008, Faber Acoustical has announced the release of SoundMeter Pro. SoundMeter Pro turns your iPad, iPhone, or iPod touch into a handheld data-logging sound level meter (SLM), data-logging noise dosimeter, and real-time analyzer (RTA).

SoundMeter Pro works with built-in or external measurement microphones to deliver reliable sound level measurements, including time-weighted and equivalent sound levels in addition to percentile-exceeded sound levels and noise dose. Measured levels can be logged at intervals as small as 0.1 seconds for durations of up to two weeks (longer measurement durations may require larger logging intervals). The built-in Octave tool performs sound level measurements in whole or 1/3-octave frequency bands.

In a recent article published in the Journal of the Acoustical Society of America, NIOSH researchers found that, out of over 130 sound measurement apps for iOS, “SoundMeter is the app best suited for occupational and general purpose noise measurements.” SoundMeter Pro builds on everything SoundMeter has to offer.

With the built-in or headset microphone, SoundMeter Pro can measure peak sound levels of up to approximately 130 dB. Results may vary between iOS devices and headset microphones. External microphones may enable the measurement of much higher sound levels.

SoundMeter Pro also includes various features that users have come to expect from Faber apps, including the ability to save measurement data to CSV, TXT, or MAT files, save measurement displays to high resolution PDF files, switch between three different color schemes, and calibrate microphone input sensitivity. Exported data files may be retrieved from the iOS device via iTunes File Sharing or by enabling the app’s built-in file server and downloading the files to another device or computer via a standard web browser. The built-in signal generator tool further extends SoundMeter Pro’s utility by producing any of various test signals, including white noise, pink noise, frequency sweeps, and periodic waveforms.

Faber Acoustical has simultaneously announced the availability of SoundMeter 5.0. The new version of SoundMeter adds support for a new Data Logging Upgrade, which is available via in-app purchase. SoundMeter Pro includes all the functionality of SoundMeter 5 with all its available in-app purchase upgrades. Although both apps run on iOS 6, each also features a user interface tailored for iOS 7.

NOTE: Although it has been designed to do so, SoundMeter Pro is not guaranteed to meet ANSI or IEC standards for sound level meters. These standards require conformance of the entire measurement system, including software, hardware and microphones.

The built-in and headset microphones are suitable for certain, basic sound level measurements, but high precision external microphones may also be used with appropriate audio accessory hardware. Even though default sensitivity values are included for the built-in and headset microphones, for best results, SoundMeter Pro should be calibrated before use. Sound levels may be off by a few dB when using the default microphone sensitivity.

SoundMeter 4.1 offers percentile-exceeded sound levels

SoundMeter 4.1, which is now available for download on the App Store, offers percentile-exceeded sound levels (Lx) via in-app purchase.

With the new upgrade, SoundMeter can display L10, L50, L90, or any percentile between 1 and 99. Percentile exceeded sound levels are also available in the Octave Analyzer tool (sold separately).

Also new in SoundMeter is the ability to set the meter to automatically stop after an arbitrary amount of elapsed time from 1 second to two weeks.

The Dosimeter and Octave Analyzer tools (sold separately) can also be set to automatically stop after a user-defined period of time.
